I'm embarrassed, but this was indeed part of the issue. Having
restarted, I received 3 spam mails. One was correctly filtered to "spam"
(victory!) but the other two still went to "inbox."

Checking the message headers, I see that the correctly filed spam
message had an "X-Spam Level" of "****". The unidentified spams were
logged as level "***". Yet, to my eye, they are all obvious spams.

I feel I'm on the road now, but is there a way to improve
performance?

Thank you again.
